Mrs. Don-o, I already posted this link in another thread relating to this issue, but I want to share it with you here too (if you haven't already seen it there or on EWTN). The link is to the youtube version of the EWTN show "World Over" with Raymond Arroyo aired last night (08-02-18). In it, Arroyo discusses this death penalty change issue with Father Gerald Murray (canon lawyer, and priest of the Archdiocese of New York), and Robert Royal (editor-in-chief of "The Catholic Thing"). They are very troubled by this decision by the Pope, and give some of their reasons why. Hope you find their discussion interesting.
Here's that link:
